TE Connectivity 103080-2 Rectangular Connector Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity 103080-2 is a shrouded vertical rectangular connector header designed for through-hole mounting applications. This component is a 4-position connector with 0.100" (2.54mm) pitch spacing, commonly used in board-to-board and cable interconnection applications. The part operates within the AMPMODU Mod II series and features male pin contacts with tin-lead finish.

The 103080-2 carries an obsolete product status. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production requirements for legacy systems and new designs requiring compatible interconnection solutions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 103080-2 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (4)
• Pitch spacing (0.100" / 2.54mm)
• Mounting method (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)

Electrical Performance:

• Current rating (3A minimum)
• Operating temperature range (-65°C ~ 105°C minimum)
• Material flammability rating (UL94 V-0)

Physical Dimensions:

• Contact length specifications
• Insulation height
• Overall contact length
• Contact shape (Square)

The substitute part 5-103080-2 maintains full equivalence across all mechanical, electrical, and dimensional parameters. The primary distinction between the main part and substitute is product status (obsolete versus active) and contact finish composition (tin-lead versus tin).

Parameter Comparison

Engineering Selection Recommendations

The 5-103080-2 is the direct substitute for the obsolete 103080-2. Both parts are manufactured by TE Connectivity within the AMPMODU Mod II series and maintain identical mechanical, electrical, and dimensional specifications.

Product Status Consideration: The 103080-2 is classified as obsolete, while the 5-103080-2 maintains active product status. For new designs and ongoing production support, the 5-103080-2 is the appropriate selection to ensure long-term component availability and supply chain continuity.

Compliance Distinction: The 5-103080-2 carries RoHS Compliant certification, whereas the 103080-2 is marked as "Not applicable" for RoHS status. This distinction reflects the active versus obsolete classification and regulatory alignment of the substitute part.

Contact Finish Difference: The primary technical distinction is the contact finish composition. The 103080-2 features tin-lead finish on both mating and post contacts, while the 5-103080-2 uses tin finish. Both finishes maintain the same thickness specification (100.0µin / 2.54µm) and provide equivalent electrical performance and reliability within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Are the 103080-2 and 5-103080-2 mechanically interchangeable?

A: Yes. Both parts are identical in connector type, position count, pitch spacing, shrouding configuration, and mounting method. They are fully mechanically interchangeable in board-to-board and cable interconnection applications.

Q: What is the significance of the contact finish difference between tin-lead and tin?

A: Both contact finishes meet the specified thickness requirement of 100.0µin (2.54µm) and deliver equivalent electrical conductivity and contact resistance performance. The tin finish on the 5-103080-2 reflects modern RoHS compliance standards, while the tin-lead finish on the 103080-2 represents the original formulation. The functional performance difference is negligible for the specified operating conditions.

Q: Why is the 103080-2 marked as obsolete?

A: The obsolete status reflects the part's discontinuation from active manufacturing. The 5-103080-2 serves as the active replacement, maintaining full electrical and mechanical compatibility while incorporating current manufacturing standards and compliance certifications.

Q: Can the 5-103080-2 be used in legacy designs originally specified for the 103080-2?

A: Yes. The 5-103080-2 maintains complete compatibility across all critical parameters: connector type, contact configuration, position count, pitch spacing, mounting method, electrical ratings, and operating temperature range. No design modifications are required.

Q: What is the packaging difference between these parts?

A: The 103080-2 packaging is not specified in the available documentation. The 5-103080-2 is supplied in tube packaging. Confirm packaging requirements with your procurement specifications.

Q: Are both parts suitable for the same current and temperature applications?

A: Yes. Both parts carry identical current ratings (3A) and operating temperature ranges (-65°C ~ 105°C). They are functionally equivalent for all electrical performance requirements.

Q: What is the MSL rating for these connectors?

A: Both parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity limitations during storage or handling.
